Energy-saving rod mill is generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns.To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced.Various classifiers, such as screens, spiral classifiers, cyclones and air classifiers are used for classifying the discharge from ball mills.Ball mill is an efficient tool for grinding many materials into fine powder.The ball mill is used to grind many kinds of mine and other materials, or to select the mine.It is widely used in building material, chemical industry, etc.There are two ways of grinding: the dry process and the wet process.It can be divided into tabular type and flowing type according to different forms of discharging material.
The ball mill is the key equipment for the grinding of iron ore after crushing, and the grinding process is the important process of iron ore sorting.
1.The quartz ball mill uses a grooved ring-shaped lining plate, which increases the contact surface of grinding balls and ore, strengthens the grinding effect, reduces energy consumption.
Preparation of pulverized coal as fuel with an intermediate bunker is shown in below fig.1.The fuel moves to the automatic balance and then goes to the feeder and ball mill through which hot air is blown.Air heater dries the pulverized coal and carries it from the ballmill to the separator.
Batch ball mill manufacturers of liming company, rod ball mill; cement ball mill; ball mill continuous ball mill; use of batch type ball mill:.
Much quantity of ball mill will be need following the domestic economy developing.Manufacturers in china actively import advanced equipment in the crushing production line, so the advanced stone crushing machines and sand making machines are entering into our country fast.With many years in researching and innovating, henan hongxing machinery company continually promotes large advanced hard-wearing ball mill, which specializing in crushing hard stones, such as pebbles, heluanshi, granite, granite, comprised, limestone and other harder materials and are applied in the sand making factories, ore dressing factories, stone factories, coal factories, powder making factories and other large construction projects in china.
Cement ball mill is also referred to as cement mill.It is mainly used to process the raw materials used in cement production, such as cement clinker, gypsum, slag and so on.most cement raw materials react to water, which affects the quality of cement.The dry cement process is often used to produce cement.
According to the fineness requirements of discharged material, the shift production capacity of the grinding machine can be adjusted between 0.6-176 tons.Ball mill production capacity can be adjusted between 0.65-615 tons.
The gold mining equipment includes: jaw crusher, hammer crusher, roller crusher, impact crusher, vertical crusher, cone crusher, ball mill, vibrating screen, spiral separator, flotation machine, mining agitation tank, ore feeder, concentrator, mine hoist, mining conveyor belt, pre-watering into a ball plate, spiral chute, beneficiation shaker, washing machine and other equipment.
Modern rotary mills make apply the same principle by tumbling loose grinding elements around in a closed drum to which the charge material is added.Common examples are rod and ball mills, both of which are of the rotary drum type which rely on internal grinding agents to achieve their milling action.Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action, the rod mill uses steel rods lying within the drum and parallel to its axis.When the drum rotates, these rods roll around inside it, thereby crushing the feed material between them.
Aside from common ball mills there is a second type of ball mill called planetary ball mill.Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes.A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel.The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1 or else).The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called coriolis forces.The difference in speeds between the balls and grinding jars produces an interaction between frictional and impact forces, which releases high dynamic energies.The interplay between these forces produces the high and very effective degree of size reduction of the planetary ball mill.
Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
